Property Description
Parameter type Big integer
Syntax SHARED_POOL_RESERVED_SIZE = integer [K | M | G]
Default value 5% of the value of SHARED_POOL_SIZE
Modifiable No
Range of values Minimum: 5000

Maximum: one half of the value of SHARED_POOL_SIZE

SHARED_POOL_RESERVED_SIZE specifies (in bytes) the shared pool space that is reserved for large contiguous requests for shared pool memory.

You can use this parameter to avoid performance degradation in the shared pool in situations where pool fragmentation forces Oracle to search for and free chunks of unused pool to satisfy the current request.
